To add a positive test case we need `taskgroup` directive which is not added hence skipping the test.
This is a dependency for `taskgroup` construct.

Valentin Clement aa179d8099 [flang][openmp] Separate memory-order-clause parser creating OmpClause node
This patch introduce the separate parser for the memory-order-clause from the general
OmpClauseList. This parser still creates OmpClause node and therefore can use all the feature
from TableGen and the OmpStructureChecker.
This is applied only for the Flush construct in this patch and it should be applied for
atomic as well.

This is the approach we disscussed several time during the weekly call.

Tim Keith 99aa87a5b5 [flang][NFC] Simplify semantics test scripts
There were several different ways of handling the option to f18 to
find predefined modules:
- test_errors.sh was created by cmake substituting
  FLANG_INTRINSIC_MODULES_DIR into test_errors.sh.in
- some tests used the flang script which has the option built it
- some tests used %f18_with_includes which was replaced by the path
  to f18 plus the -I option
- some included -I../../include/flang in their run command

To make this more consistent, change %f18 to include the
-intrinsic-module-directory option and use it everywhere, including
to replace %flang and %f18_with_includes. This requires changing all
of the invocations of the test scripts to put %f18 at the end so that
it can expand to more than one argument.

This eliminates the need to generate test_errors.sh which means we
don't need flang/test/Semantics/CMakeLists.txt or the %B substitution.
That makes the test_errors.sh command like the others, replacing
%B/test/Semantics/test_errors.sh with %S/test_errors.sh.

Also remove the OPTIONS: functionality as custom options can be included
in the RUN: command. And remove -I/../../include/flang as that is now
always included.

Patrick McCormick 6c16aa4f67 [flang] A rework of the cmake build components for in and out of tree builds.
In general all the basic functionality seems to work and removes some redundancy
and more complicated features in favor of borrowing infrastructure from LLVM
build configurations. Here's a quick summary of details and remaining issues:

  * Testing has spanned Ubuntu 18.04 & 19.10, CentOS 7, RHEL 8, and
    MacOS/darwin.  Architectures include x86_64 and Arm.  Without
    access to Window nothing has been tested there yet.

  * As we change file and directory naming schemes (i.e.,
    capitalization) some odd things can occur on MacOS systems with
    case preserving but not case senstive file system configurations.
    Can be painful and certainly something to watch out for as any
    any such changes continue.

  * Testing infrastructure still needs to be tuned up and worked on.
    Note that there do appear to be cases of some tests hanging (on
    MacOS in particular).  They appear unrelated to the build
    process.

  * Shared library configurations need testing (and probably fixing).

  * Tested both standalone and 'in-mono repo' builds.  Changes for
    supporting the mono repo builds will require LLVM-level changes that
    are straightforward when the time comes.

  * The configuration contains a work-around for LLVM's C++ standard mode
    passing down into Flang/F18 builds (i.e., LLVM CMake configuration would
    force a -std=c++11 flag to show up in command line arguments.  The
    current configuration removes that automatically and is more strict in
    following new CMake guidelines for enforcing C++17 mode across all the
    CMake files.

  * Cleaned up a lot of repetition in the command line arguments.  It
    is likely that more work is still needed to both allow for
    customization and working around CMake defailts (or those
    inherited from LLVM's configuration files). On some platforms agressive
    optimization flags (e.g. -O3) can actually break builds due to the inlining
    of templates in .cpp source files that then no longer are available for use
    cases outside those source files (shows up as link errors).   Sticking at -O2
    appears to fix this.  Currently this CMake configuration forces this in
    release mode but at the cost of stomping on any CMake, or user customized,
    settings for the release flags.

  * Made the lit tests non-source directory dependent where appropriate. This is
    done by configuring certain test shell files to refer to the correct paths
    whether an in or out of tree build is being performed. These configured
    files are output in the build directory. A %B substitution is introduced in
    lit to refer to the build directory, mirroring the %S substitution for the
    source directory, so that the tests can refer to the configured shell scripts.

Luke Ireland f1a8eae3b6 [flang] Port all remaining regression tests to lit
We have re-classified a subset of the regression tests as unit tests and
now we are porting the remaining ones.

Test discovery and running is now performed by lit rather than ctest.
The tests continue to use their original scripts with minor
modifications. Most of the changes were mechanical and so scripted.
A few changes were made by hand. Details

Manual:
  * modfile09-*.f90 tests depend on being run together as some tests have
    dependencies on modules created by other tests. This will need
     separating out when porting away from test_modfile.sh, but for now,
     added modfile09-*.f90 to the Inputs directory and added a single
     tests modfile09.f90 to hold the run line.
  * getdefinition03-a.f90 includes a non-test file getdefinition03-b.f90.
    Manually edited the former to find the latter in Inputs so as to add
    only one test.
  * Same pattern for getsymbols03-{a,b}.f90

Auto:
  * Remaining tests have a lit RUN line added to them based on the type
    of test they are.
  * Failing tests also have an XFAIL line added to them.
  * Generic tests have their pre-existing RUN lines replaced with the
    word "EXEC" to avoid conflict with the added lit RUN line.
